Title: Stabilising satd. chlorinated aliphatic hydrocarbon(s) - against metal-induced decomposition, using poly:alkylene glycol(s) and mono:alkyl ether(s)
Inventor: ALLEN CHRISTOPHER STORM
IPC: C07C67/00
Filed: 1978-08-14
Abstract: Satd. chlorinated aliphatic hydrocarbons (I) are stabilised against the known metal induced decomposition which occurs during mfr. involving distn. or vapourisation by incorporation of a polyether of formula R-(OC(R1)HCH2)n-OH (II), into the liq. and/or vapour of (I). In the formula, R is H or 1-4C alkyl; R1 is H or Me; and n is 2-20. Addn. of (II) prevents the metal induced decomposition of (I), and hence the subsequent fouling of equipment (esp. distn. columns). The method is esp. useful with (I) contg. 2C atmos, esp. in the distn. and recovery (as overhead prod.) or 1,1,1-trichloroethane in the presence of metals (and oxides and salts) and other chlorinated ethanes. In an example, addn. of diethylene glycol monomethyl ether at 100 ppm. reduced net vinylidene chloride content from >5000 ppm. to 20-25 ppm. in 1,1,1-trichloroethane refluxing in contact with metal rings and 14 ppm.

Title: Safety link for impact absorbing steering column - includes splined sliding coupling to isolate steering wheel from column during crash
Inventor: WACKER SIEGFRIED
IPC: B62D1/11
Filed: 1978-10-18
Abstract: An impact absorbing steering wheel is coupled to the steering column with a failsafe link. This link disconnects the wheel from the column in the first phase of the impact. This has the effect of isolating the steering wheel from violent wheel deflections in a serious crash and greatly reduces injury. The safety coupling has a sleeve connector with inner splines to fit over a splined ring on the steering column. Axial force above a set value pushes the splines apart and frees the wheel. The wheel is also fitted with impact absorbing mountings and padding.

Title: Cultivating mycorrhiza fungi, esp. Boletus edulis - in system with exchange of nutrients and metabolites e.g. across permeable membrane
Inventor: ERNST KARL AUGUST DR ING
IPC: A01G1/04
Filed: 1979-01-08
Abstract: Method for cultivating mycorhiza fungi comprises regulating the metabolism of the fungi in a cultivator or growth vessel with an exchange-surface system, e.g. permeable membranes or capillaries. The nutrient soln., contg. inorganic and/or organic materials and the metabolites are separately supplied and removed from the container. The fungi are arranged on the exchange-surface system. The nutrient soln. may be recirculated via a reserve tank, or the spent nutrient is collected in a separate tank and not recycled. The compsn. of the nutrient soln. can be altered during the process (e.g. by adding fungicides or bactericides) and the gas atmos. can also be modified with CO2 and/or O2. A growth vessel for this method is also claimed. The method is esp. useful for growing edible mushroom Boletus edulis. The system mimics the natural conditions for this species (which grows on tree roots with exchange of sugars from tree to fungus and of inorganic salts from fungus to tree).

Title: Optical fault detection in glass bottles - using scanning beam mirror rotation and integrating sphere and photodetector evaluation
Inventor: MIYAZAWA TAKASHI
IPC: G01N33/00
Filed: 1979-03-16
Abstract: An arrangement detecting faults in glass bottles, eg. those for alcoholic drinks having been returned for re-use, has a light source and optical system and is capable of detecting all types of possible faults in bottles or similar objects. Conventional devices tend to miss faults in side walls and their sources are directed at the base of the object. Two oscillating mirrors (14, 15) in the path of the light (11) from a source (10) imparts a circular or spiral scanning motion to the light beam. The beam can thus scan the desired surfaces of the object (22) under test. The light from the object is evaluated for faults in an integrating sphere (24) with a photodetector (27) receiving light reflected from the sphere's inner surface.

Title: Combination lock with numbers displayed in windows - has combination display becoming obscured prior to lock mechanism releasing action
Inventor: HERRIOTT LESLIE VICTOR
IPC: E05B37/02
Filed: 1979-05-25
Abstract: When the blocking element is in its release position and the lock is opened the user has access to the display elements through the opening. In this position the rotation of the display elements is not transmitted onto the setting elements by the action of pins. The user can alter the position of each display element in relation to the setting element. Each number on the display elements is duplicated so as to appear either through an opening or through windows. When the case is closed and the flap is in the opening the position of any display element in relation to the setting element cannot be altered. When the blocking element is in its release position there is no meshing connection between setting elements and the display elements.
Patent DE-2926920-A1 (DE)
Title: Endoscope incorporating solid optical fibres - has eyepiece fitting over external end of viewing fibre, which is parallel to hollow tube available for medical use
Inventor: MATSUO KAZUMASA
IPC: A61B1/00
Filed: 1979-06-30
Abstract: Endoscope employing optical fibres normally have the eyepiece mounted at the side of the near end of the instrument. This requires an additional prism to deflect the light beam. Moreover precise physical alignment is made more difficult by the flexible nature of the fibre. This is overcome by making the fibre into a solid rod which terminates directly at the eye piece. The optical fibre (22) which receives the reflected light is bent at an obtuse angle and terminates at the eyepiece (14). It is solid throughout its length. A slit (26) in the side of the tube (13) which forms part of the eyepiece unit allows the latter to be pushed over the fibre during assembly. The illuminating and viewing fibres (22,24) both lie parallel to a hollow tube (18) of metal or stiff plastics to permit the introduction of a catheter or surgical instrument.

Title: Layered insulation for hot gas conduit from reactor - is compressed by bolts at corners and centres of cover plates
Inventor: SCHOENING JOSEF DIPL ING
IPC: G21C11/08
Filed: 1979-12-11
Abstract: A large rectangular section conduit for high pressure and temp. gas travelling from a gas-cooled reactor or breeder passes round a right-angle bend towards a circular section steam producer and is concentrically surrounded by a channel for cold gas travelling in the opposite direction. The hot conduit is lined with multiple thermal insulation layers sepd. by intermediate sheets and internally covered by square plates held on a support structure by through bolts, compressing the insulation. Each bolt is located where four cover plates meet and carries two spaced washers between which the plates are gripped. The gaps between cover plates are covered by strips. At the centre of each plate is a further insulation-compressing holding bolt passing through washers. Between the layers are further washers and spacer rings. The retaining and covering washers are coated with wear-resistant material. Low stress and wear increase insulation life. The hot-gas support structure is relatively cool and hence needs less expensive material.

Title: Fibre body moulding - uses some fibres with fusible surface to give thermal bonding during press-moulding
Inventor: EISELE DIETER
IPC: D04H1/544
Filed: 1980-02-27
Abstract: The blanket of carded or cross-laid fibres, contg. at least a proportion of fibres with a thermally-fusible mantle material, is pressed into shape together with heat. Thus the moulding and bonding processes occur at the same time. The fibres to be used are a bi-component mantel and core (10, where the core (11) has a higher m.pt. The cladded-core fibres (10 form at least 25% of the whole fibre content of the material for moulding. Pref. polypropylene is used for the cladded-core fibres (10). The two sections of the moulding press are heated to different temps., and their surfaces are profiled to shape the material being moulded. The process allows moulded fibrous components to be mfd. economically, without any added bonding agent. The heat bonds the material while it is being press-moulded, and the moulding is then cooled after removal from the press.
